Considering you did not receive a reply when you asked your question, yes, you should consider all those patterns acceptable for any trout or salmon fishing you might try, whether European brown trout, steelhead, landlocked salmon, and even warm water fisheries for bass, etc.

Some of us were expecting a commercial angle to arise at any moment. If you in fact just bought those in China for personal use, and took the trouble to photograph and scan them just to ask us if they would catch fish, then my apologies for my lack of an enthusiastic reply as they are indeed great looking flies. In fact I will be using goose quill with scintilla based legs in my own fly patterns after having looked at these patterns. Whether they will catch fish is kind of obvious to a fisherman, so again forgive us for thinking there might have been an angle for promotion there.
